ABSTRACT:
A self-contained alarm system for a boat outboard motor connected to a boat transom by clamps is easily retrofit onto an existing boat. A housing of tough non-conductive material (such as polycarbonate) contains a power source (such as a battery) and a signalling device (such as a horn or lights). The housing includes a hub and a pair of arms, which are pivotal with respect to each other about the hub, or the arms can be sliding members, sliding relative to each other. Electrical contacts are provided adjacent the end of one or both of the arms, the contacts engaging clamp pads. If the clamp pads are moved out of operative engagement with the contacts, the battery activates the signal device. A circuit for sensing an open circuit condition may interconnect the signal and battery may be provided, or the contacts may be designed so that a closed circuit actuates the signal.
